REMINGTON TYPEWRITER COMPANY, OF ILION, YORK, A COBPQRAr TION OF NEW YORK.

To all 'iulz'om it may concern:

Be it known that I, J soon FELBEL, citizen of the United States,- and resident of the borough of Manhattan, city of New *York, in the countysoif New'York and State of New York, have invented certain new and useful Improvements I in Type-lVriting Ma chines, of which the following is a specification; .4 a

"My invention relates to 'typewriting' machines and more particularly to devices for controlling the work sheets. One object of the invention is to simple and efficient means for properly controlling and handling the sheets' in doing condensed record work. p I A further objectof the invention is to pro- I vide devices "in the nature of attachments tying the structural features of said'ma which may be readily a plied to existing Styles of typewriting mac in: without modi- .chines.

' The constructions thus far described are L common to the -Monarch machine and fur: ther detailed description thereof is deemed Holding or clamping fingers, members or reference numeral 21, are preferably mounted for adjustment longitudinallyof the platen. In the present instance each clamp;

and is pivoted at 2:2 to an arm 12, the pivotal axis of the clamping members extending transversely of the platen so that said m'em bcrs are pivoted, lo swing toward and away from the platen in a plane which cuts through the platen longitudinally thereof. Each clamping member-comprises an engaging or pressing'portion E23 .vhieh projccls inwardly from the pivot toward the enter of the platen; and when in engaging position the part 23 extends parallel with the axis of the platen and parallel with the plate-19. Each clamping member prefer: ably has angular bends 24, 25 and 26, the part '26 constituting a finger piece by which the clamping member may-be turned on its- Ears 27 are formed on the portion 25 offorated tor the reception of the pivot pin which is connected at its ends to arms 29 to a base'plate 30, which in turn is secured by Screws 31 to the upper side of the arm or support 1 2.' A spring 32 is securedat free end of the spring is'adapted to bear against either of the portions 25'or 26 of the clamping member, depending on the po sition of the clampingin'ember; thus ,;when .the clampingmember is in the operative position shown in full, lines in Fig. 3 the spring'coiiperates with the part 25 and tends to maintain the clamping device'in' the oper ative position, that is, with the portion 23 ofv theelamping member under pressure agamst the platelfl or the paper thereon.

Vlhen the clamping member is turned onits pivot to .the inoperative position, shown a in dotted lines in Fig. 3, the spring '32 cooperates with the. part 26 to maintain the clamping member in suchposition. construction of each of the clamping mem The" bers, paper fingers, feed roller 14 and'the supports therefor is the same, except that the clamping members-project in opposite. directions andthe description of one of the clamping members and assbciat'ed parts ap plies equally to the other. The construction -is such that thefeed'rollei's l4: and paper 1 fingers 16' coiiperate with the paper at the pposite side edge portions thereof in the;

usual manner.

tudinally of the platen' in' order that the' In the use 'of ther'devi'ces' tor condensed '4 feed rollers and-paper fingers-may properly I cooperate with work sheets of the width to be employed. From an inspection of F 1 it will be seen. that the condensed recordsheet a'which lies next to the platen, is of less width than the invoicesheet 'Z) and is of a width materially less than the length of the platen; the interposed carbon sheet 0 pref-- ably being of a widthwhiehco-rresponds to the record sheet. It will also be seen that the rulings (Z and e on the record and invoice sheets, respectively, register when the. right-hand edges of said sheets are brought,

into register, so that the items or, amounts written within the respective columnsupon the invoice sheet will be reproduced through the interposed carbon or transfer sheet in corresponding columns on the record or journal sheet. The-sleeves 10 and the parts carried thereby may be adjusted substantially in the manner shown in Fig. 1 so i that the parts will bear a relationto the sheets widthwise thereof such as that indicatedin said figure. The clamping members are first turned to the inoperative po- -sition shown in dottedlines in Fig. 3 and the record sheet, invoice sheet and interposed carbon sheet are introduced simultaneously into the machine with the record sheet next to the platen and the invoice.

sheet outermost where it will receive the im-.

pacts of the types. The leading edges of i the sheets may 'coincide'or a lead of the invoice sheetniay be given in the usual manner so that the first line on the record sheet may appear near the top thereof. All three sheets pass beneath the right-hand paper finger and feed roller 14:- and. all of said 5' sheets may passbeneath the left-hand paper finger and feed-roller l4 or the left-hand paper finger and feed roller may bearagainst the invoice sheet only, depending on the relative widths of the sheets, or' other circumstances. After the leading edges of the sheets pass the paper fingers and feed rollers 1 L theyleave theplatenand feed or pass over the plate 19and supporting bar 9. When the-platen has-been turned so that the invoice sheet is in aposition to receive the.' first line of writing, the operator-pro ceeds to fill in'the' invoice which is duplicated on the recordsheet. The platen may then be'given' a double line space to, provide.

20 a proper space between the to ies of the dif-.

other words, the'engaging'portions, fingers or blades'of the clamping members are inserted between the invoice and carbon sheets and caused to bear against the carbon sheet so as to press it and the record sheet against the erasing plate 19 and hold the last mentioned sheets against movement while the completed invoice sheet is removed from the machine. This .removal may be accom: plished by throwin' and locking olf the feed rollers 6 and 7, an 14 if used, and pulling on theinvoice or outer sheet alone. After 49 the removal of-the' invoice, a new invoice sheet is introduced into the machine while the platen, record and carbon sheets remain fixed or "stationary, When the newlyintroduced invoice sheet has been )roperly adjusted to receive the'first line 0 writing the feed rollers are unlocked or restored to writing position and the clampingmembers are turned to the inoperative position to redense the carbon and record sheets and the 5 operator proceeds as before 'to fill in the invoice which is duplicated on the record sheet. Vhen the second bill is completed the operator proceeds as beforeand so on until the record sheet has been filled when a new record sheet may be introduced with a bill-and carbon sheet as before.

While I have described one method of using the devices for condensed record work it should be understood that this method may be varied. For instance, it may/ be 'found desirable to use comparatively short carbon sheets of the same width as the in-' voice sheets employed. In this event the carbon sheet may be removed with each in- 5 voice sheet as it isfilled in and the clamp-i .tia l change therein.

- While I have shown the use of two' clamping device or devices instead of bearing on the carbon and record sheets willbear only on the record sheet so as to clamp said record sheet while the invoice and carbon sheets are removed.

The introduction and proper positioningand removal of the invoice sheets are not substantially diuerent from what would be the case were the condensed record method not employed, except that the platen is .not turned either to introduce, position or,remove the successive invoice sheets. The casting o'fi 'of the feeding devices leaves a clear passage for the introduction,'adjustment-and removal of the invoice sheets 80 while the record sheet remains held to the platen; Thus there is no liability of disturbing the record sheet during'these operations.

- From the foregoing description it will 5 also be observed that the devicesare simple in COIIStILlClLIOH, easy of operation, inexpem sive -to manufacture, and may bereadily applied to existing machines without substaning devices 21, each adjustable longitudinally of the platen with the carrier for thepaper fingerlG and the feed rollers lfi, it should be understood that only oneof these clamping devices. may be found necessary. lfn Fig. 4 I have showna modified con: struction of my invention in which the clamping member'is made of two relatively adjustable parts, the parts being united by 199 a screw 34; which passes freely through a slot 35 in one member and enters a-tapped hole in the other member. By-this construction .I am enabledto effect a relative adjustment 7 between the" two parts of each clamp in 1 5 order that the engaging or pressure member 23 thereof may eiiiciently engage the paper and with the desiredpressure. In this con struction I have shown the clamping mem her co-acting with the top of the platen-5110 instead of with thej'pl'ate 19', as inthe construction previously described.- It may be .found desirable in some instances to cover.

the engagin portion of the clamp with a sheath of sol t rubber or like material 36, in order better. to grip and hold the carbon and record sheets against movement. Ihave also shown in Fig. 4 a difi'erenif form of spring means for retaining the clamping-device in either the operative or inope'ratlve position: Thus, a headed plunger 37 works in an opening 38 in the arm-12"on which the clamping member is pivotally supported. A coiled expansion. spring 39 surrounds the plunger and bears at one end against the head of -t he plunger and at its opposite end against the supporting arm] 12. Bythis construction the head of the spring pressed plunger bears against the part 25? or 26 of the clamping member to 3 with ears-42 by which a pivot pin 43 is sup-f hold the member eithe'r in the operative or 1 above the platen and on the discharge side inoperative position; andto exert the pres- 1 thereof, it will be observed'that the record sureon the clamping member'to hold it un der pressure when it is in the operative position. The arm 12 in this construction corresponds-to the arm 12 in the construction previously described and the operation of the device, shown in Fig. 4, is thesame as in the construction;- previously described' The features shown in' Fig. 4 may of course be incorporated in the form 'shown in Figs. 1-3.

In Figs. 5 and 6 I have shown a still further 'modification of the construction in which the devices do not extend so high as in the previously described constructions. Thus,- a sheet metal bracket 40, which is shownin detail in Fig. 7, issecured; by

screws 41 to the supporting arm 12 of a paper finger l6 and feed roller 14. This ported, said pin passing freely through openings in ears 44 struck up from a sheet metal clamping member, which is shown in detail in F ig: 8', so as to provide a pivotal support for said clamping member. A spring '45 is secured at one end, as at 4.6, to the bracket 40 and the free end of said spring bears either against afaee 47 or a face48 of the clamping member so as to retain it either in the operative or inoperative position as desired; Th'efree end ofthe clamping finger 49 1s slightly upturned as at 50 to provide a finger piece or means whereby the clamping member may be lifted out of engagement with the plate 51' (or the platen if the plate be not used) and turned to the inoperative position. In Fig. 6 the paper is not illustrated for convenience. The paper fingers. feed rdll'er and arnr 12* are constructed and mounted upon the supporting bar 9 as in the constructionshown in Figs. 1, 2 and 3. The operation of the devices shown in Flgs.

and 6 essentially the same as in the construction shown in Figs. 1, 2 and 3 and need not be repeated.

It 'will he noted that the pile or set of superposed work shees is fed into the platen over the paper table 8 and between the feed rollers? and (i and the platen. and between the, paper lingers l6 and the plateiu'and be tween the feed roller 14 and the platen, (if

the feed roller 14 be used, and that, in the course of the writing, the platen is line spaced step-by-step as usual and the paper discharged from the platen upwardly andrearwardly 'over the plate or bar19, which,

with the clamping member. is situated over 1 may he raised to release the under sheet and the platen and on the discharge side thereof.

In the present construction and in the Monarch machine the printing point is at the I l I 'difierent from a. -as opposed theret that the clamping device herein is adamper sheet holding eontrivance purely; that is to say, thatit does not in any manner assist in the feeding of the paper; on the contrary,

is directly'opposed to a feeding operation and is independent of the paper feed mechanis'm. Therefore where the term clamp or sheet holding contrivance or the like is employed it is to be construed as something paper feeding device and It will be understood that in the Monarch billing or condensed record machine, means are provided for simultaneously casting off thefeed rollers 7 and 6 and the paper blade or scale bar not shown), and in some 111- s'tancesa-lso the paper'fingers .16 and in consequence of this arrangement or provision iii the machine the billing'or invoice sheet, which is usually the outside sheet of the pile, may be readily removed from'the machine while the sheets, underneath are by means of my novel device held clamped either directly upon the platen or'directly upon the erasing plate 19;; and while the feeding mechanism is thus cast off thenew' bill or outside sheet may be readily introduced from the rear of the machine and brought to proper position with reference to the sheets underneath, whereupon the feeding devices are released or brought back into cooperation with the paper on the platen and the clamp is turned to an inoperative position.

It. is not always necessary that the clamp, in normal position. stand-in the dotted line position shown at Fig. 3; It may lie in direct contact with the erasing plate and all of the paper may be fed thereover; then when it may he desired to clamp therecord sheet and its superposed carbon. if necessary, all of the sheets may be pulled forwardly toward the operator; then the top or outside sheets are separated.- the clamp swung up to the dotted line position in Fig. 3, the record sheet audits carbon laid upon the'erasing plate and then the clamp may be swungdown to hold the last two mentioned sheets only, caving the outside sheet free. Then and 'the free sh et removed. -After the inlroductiou of another bill sheetthe clamp noted that the pile of paperto be written 71- It will be seen' that inj'all of the construe tions shown the clamping members are piv otedat their outer ends so that the pivot and support for each member are arranged laterally beyond or outside the side edges of the sheetsemployed in the machine; that each o-f ;,th e-clamps is. hand operated; that thework'sheet holding device'shown in Fig. 4: cooperates with the platen to hold the sheets thereon, whereas the clamping devices shown in the remaining figures cooperate with the plate 19 or with means independent of the platen, and that in all forms shown certain of the sheets pass over the engaging portions of the clamping devices and certain other of the sheets lie under such engaging portions of the clamping devices:

Various changesmay be made without departing from the spirit and scope of my invention.
